dynamic changes, without liver graft congestion/dysfunction, and was associated with significant reduction in postoperative pulmonary complications.
Stepwise alveolar recruitment identified the optimal positive end-expiratory pressure to improve lung mechanics and oxygenation with minimal hemodynamic changes, without liver graft congestion/dysfunction, and was associated with significant reduction in postoperative pulmonary complications.Acute kidney injury is a significant cause of morbidity after orthotopic liver transplant. Early extubation after liver transplant may have a beneficial effect on postoperative renal function. This may be the result of reduction in vasopressor-mediated vasoconstriction used to counteract the hypotension associated with sedative use and the effects of positive-pressure ventilation. Previous studies explored advantages of early extubation after liver transplant but focused on resource usage rather than clinical benefit. This study was designed to determine the association between fast-track extubation and reduction in postoperative vasopressor requirement and whether this had any association with acute kidney injury incidence or renal replacement therapy requirement.
Data were collected from 144 orthotopic liver transplants. A propensity-matched case-control analysis was conducted on a subgroup of 33 patients who were fast-track extubated and with 33 propensity score-matched control patients who were not. Tport.
This is the first study to reveal a significant association between fast-track extubation and reduced postoperative vasopressor requirement. Additionally, this was associated with a trend toward reduced renal replacement requirement after liver transplant. It suggests that early extubation may not just be a resource benefit to an institution but may convey a clinical benefit to patients through a reduction in organ failure and requirement for organ support.Renal transplant is considered the best therapeutic option for suitable patients with end-stage kidney failure. Hematological complications that occur after kidney transplant include posttransplant anemia, leukopenia, neutropenia, and thrombocytopenia. Severely persistent leukopenia and neutropenia events predispose patients to infection, including opportunistic infections. The mainstay tactic for such complications is to reduce the burden of the immunosuppression by the offending agent, but this tactic is associated with increased risk of acute rejection. Given the absence of laboratory investigations to specifically identify the culprit, a complete withdrawal of these agents may be the ultimate diagnostic option. Future therapeutic strategies, however, should focus on reducing the immunosuppressive burden, the introduction of less myelotoxic agents, early recognition, and prompt treatment of infectious episodes. This will help in the optimization of the myelopoietic function and normalization of the hematological profile, resulting in better allograft and patient survival.Autosomal recessive polycystic disease is a rare hepatorenal disorder. End-stage renal disease and liver fibrosis are serious presentations of this disease. Here, we report 2 brothers with autosomal recessive polycystic disease who presented with abnormal abdominal protrusion and hepatosplenomegaly during infancy and eventually underwent renal transplant. Congenital hepatic fibrosis and nephromegaly followed by renal failure developed, after which renal transplant was successfully performed. The remaining compli-cation after transplant was hematemesis and melena due to esophageal varices. Autosomal recessive polycystic disease has a broad spectrum of symptoms; similar pre-sentations with manifestations in siblings may explain some unknown genetic causes of this rare disease.Acute kidney injury (AKI) is a common complication after lung transplantation (LTx) which is closely related to the poor prognosis of patients. We aimed to explore potential risk factors and outcomes associated with early post-operative AKI after LTx.
A retrospective study was conducted in 136 patients who underwent LTx at our institution from 2017 to 2019. AKI was defined according to the Kidney Disease Improving Global Outcomes (KDIGO) guideline. Univariate and multivariate analyses were conducted to identify risk factors related to AKI. The primary outcome was the incidence of AKI after LTx. Secondary outcomes were associations between AKI and short-term clinical outcomes and mortality.
Of the 136 patients analyzed, 110 developed AKI (80.9%). AKI was associated with higher baseline eGFR (odds ratio (OR) 1.01 (95% confidence interval (CI) 1.00-1.03)) and median tacrolimus (TAC) concentration (OR 1.15 (95% CI 1.02-1.30)). Patients with AKI suffered longer mechanical ventilation days (?=?.015) and ICU stay days (?=?.011). AKI stage 2-3 patients had higher risk of 1-year mortality (HR 16.98 (95% CI 2.25-128.45)) compared with no-AKI and stage 1 patients.
Our results suggested early post-operative AKI may be associated with higher baseline eGFR and TAC concentrations. AKI stage 1 may have no influence on survival rate, whereas AKI stage 2-3 may be associated with increased mortality at 1-year.

The results showed that the adsorption was the pseudo second-order kinetic process, indicating that chemisorption was the dominated process, which followed the Langmuir isotherm model and the highest Ni2+ adsorption capacity of PPCB reached 35.6?mg/g. By KMnO4 modification, the corncob was oxidized to generate carboxylates, and the MnO2 (reduction product) was loaded on the modified corncob, both carboxylates and MnO2 increased the Ni2+ adsorption capacity of PPCB. The molecular dynamic results indicated the carboxylate structures had the strongest adsorption capacity. Moreover, the Ni2+ removal efficiency of KMnO4 modified biomass decreased linearly with the increase of lignin content in biomass, while KMnO4 modified lignin showed a good adsorption performance, indicating that the cross-linked structures between lignin and other components in the biomass could inhibit the adsorption capacity of PPCB.
